SPECIFICATION forming part of Iletters Patent No. 742,057, dated October 20, 1903.

Appiieetiei-ied July 1s, 1903.

To all whom t may concern: y

Be it known that we, HANDEL E. OWEN an ARTHURJ .SHAW, citizens of the'United States, and residents of Spokane, in the county of Spokane and State of Washington, have made certainv new and useful Improvements in Nut and Bolt Locks, ot' which the following is a speciication.

This invention is an improvement innut and bolt locks, being in the nature of de-V vices by which to fasten the bolt and the nut; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a side eleva-v tion of a rail-joint provided with our improvements. Fig. 2 is a cross-section on about line 2 2 of Fig. 1. Fig. 3 is a detail view of the bolt. Fig. 4 is a detail view of the lockingplate. of a portion of the fish-plate o1' other abutment with the locking-plate, bolt, and nut applied. Fig. 6 shows a somewhat dierent form of abutment in connection with the bolt, nut, and locking-plate. Fig. 7 isa detail perspective view of the construction shown in Fig. 5 with the locking-plate adjusted to lock the nut and bolt; and Fig. 8 is a detail perspective view illustrating the bolt, nut, and locking-plate in connection with a iiat abutment.

In Figs. 1 and 2 the abutment is in the form of a fish-plate for use on rail-joints, the fishplate A having the upright'wing B grooved longitudinally at C to form a seat for the locking-plate E. The locking-plate E is shown in detail in Fig. and is provided with a central thickened portion E', through which is formed the iattened opening E2, and with the end wings E3, projecting from the opposite ends of the thickened portion E and adapted to be bent up alongside the nut, as will be understood from Fig. l of the drawings. We prefer to provide this thickened portion E', as it forms a firm seat for the nut, at the same time furnishing the reduced end portions E3,whieh can be readily bent up alongside the nut; but

f it will be understood that the locking-plate may be as shown at F in Figs. 5, 6, 7, and 8 and be of equal thickness throughout.

In Fig. 5 the abutment G is in the form of a plate having the ribs G raised above its Fig. 5 is a detail perspective view serie] No. 166.095. No model.)

. surface and forming the recess or groove G2 Fto receive the lockingfplate.

It will be noticed that in Figs. 1 and v2 the groove or seat C is also formed by ribs C, similar to the ribs G in Figs. 5 and 7.

In Fig. 6 we dispense with the rib construction and form therecess I-I' directly in the face of the abutment H, both said construe;

tions (shown in Figs. 5 and 6) operating to prevent any turning of the locking-plate.

In Fig. 8 the locking-plate Fis not seated in the abutment I, but is free to turn there.- on, the plate'F being held from turning on the `bolt by the means 'presently described and the corners or ends of said plate F being in practice turned up Aalongside the nut to lock the same, as will be described.

The boltV J has its threaded portion flattened at J to fit the opening E of the locking-plate whether said plate be constructed as shown in Fig. 4 or as shown in Figs. 5 to 8, so that when the bolt projects through the opening E2 it willbe held from turning in the said opening. Then when the'end wings or alongside the nut the latter will be locked from turning onthe'i'bolt, so that by'one device we fasten both the bolt and nut from independent turning, and when the locking-` plate is seated in aV groove or recess in the face of the abutment and is thereby held from turning-upon the said abutment the one device locks the bolt from turning and locks the nut from turning and operates to hold the parts firmly and rigidly in position.

The construction is simple, easily operated, and will be found to effectually prevent any accidental turning of the nut or of the bolt lindependent of the nut in the use of the incorners of the locking-plate are turned up At the present time nearly all structural Work is being made of steel, and the cheapest construction necessitates use of round holes for bolts. By our invention we are able to use a round bolt to lit such openings, forming the bolt with the flattened threaded portion to fit the flattened opening in the lockingplate, thus furnishing a nut-and-bolt-locking device which can be applied with the greatest economy to structural Work, Whether it be in bridge or other structures. While roundhead bolts are in general use, it is understood nothing herein is to prevent ordinary bolts having flattened or square heads being used.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. The combination of the abutment provided with the longitudinal ribs forming a depressed channel or recess for the lockingplate, to keep the same from turning, the bolt having its threaded portion flattened, the locking-plate having an opening conforming to the flattened portion of the bolt and fitting thereon whereby the bolt is held from turning in the plate, said locking-plate having the central thickened portion to receive the pressure of the nut and the Wings of reduced thickness projecting from the opposite ends of said central portion and adapted to be turned up alongside the nut, and the nut turning on the bolt up against the lockingplate and held from turning on the bolt by the end wings ot'V said plate substantially as set forth.

2. The combination of the abutment having a groove or channel for the locking-plate, the locking-plate fitting in said groove or channel and having a central thickened portion provided With a flattened opening for the bolt and with end Wings of reduced thickness to be bent up alongside the nut, the bolt having its threaded portion flattened to fit the flattened opening of the locking-plate and the nut substantially as set forth.
